What is Blockchain – The Complete Guide

Nowadays, Blockchain is one of the most famous and discussed a thing, but several people just know about Blockchain’s existence but are unaware of its actual meaning and uses. On the internet, several guides state that they offer a complete guide regarding Blockchain, but unfortunately, they are also unable to provide complete information.

But if you want to know everything about Blockchain, then do follow this article till the end. As with the help of this article, we are going to discuss everything about Blockchain, it’s used, why it’s created, and many more things.

What is Blockchain?

In general, if we extract the name “BlockChain,” then we would be able to get that it is just a chain of blocks. But do you know it’s enough to explain the most discussed thing nowadays? I don’t think so.

For explaining to you what Blockchain has a look here, Blockchain is that thing or program in which the digital information is stored in a public database, which is its correct meaning. In the case of this definition of Blockchain, the block is stated as the digital information while the chain is stated as the public database.

Who controls Blockchain?

There are several countries that are trying to make people of their country use cryptocurrency, for doing so they are taking several steps. But no country’s government is controlling the complete blockchain platform.

Now you would be thinking that blockchain they are not controlled by any country or governments then who is? So let me tell you that Blockchain is a decentralized and open-source platform, which means that it is free to read program in which anyone can make changes. So this states that no one is controlling the blockchain platform, people from various communities are making changes on their part for usage.

What are the three pillars of Blockchain?

As you may know that everything is made with the help of some elements, functions, and supports. The same is the case with Blockchain as it has also been made, or we can say that there are three strong pillars, which are helping the blockchain platform to stand. Let us have a look at all those pillars-

1. Governance

As you all know everything has it’s rules and regulations to be followed and to make sure those platforms are following those rules there are protocols that help in the governance. The same is the case with Blockchain, as several rules should be followed while working with it.

The users had faced several problems with Blockchain when there were no governance-based systems. But nowadays it is safer than ever as everything is being governed for an enhanced blockchain platform with better safety features.

It there would have no governance. The whole blockchain platform must have become a boon for everyone, and no one must have invested or shown their interest in the blockchain platform.

2. Economics

Now, let us have a look at why and how economics is defined as the second pillar of Blockchain? So the basic working of economics is in the cryptocurrency and bitcoin area. This is because on other platforms when you contribute something to that platform, it will never give you any reward.

Hence, because of this, your data on such a platform is not safe. But in the case of Blockchain, whenever you contribute to this platform, every time you get a reward, and that could be in the form of tokens which you can convert it in any form, either in cryptocurrency or anything.

This is why economics is defined as the second pillar of economics.

3. Technology

I hope you all must be knowing why technology is called as the third pillar of Blockchain. The basic reason is that with the help of technology the overall security and scalability of this platform can be enhanced. With the help of a technology blockchain platform is easily available to its users, moreover, they can make transactions directly from any place of the world any many more things.

These were the three pillars of Blockchain, with the help of which the blockchain platform is being used all over the world, and hence we can see several enhancements in this platform.

What are the real-life uses of Blockchain

Blockchain is used for a number of things, although people just know about it’s 1-2 uses only. To know all the places where Blockchain is and can be used, have a look at the points listed below.

There are several real-life uses of Blockchain, which are being used right now in various parts of the world. But the above-listed are some of the most important ones.

The working principals for Blockchain technology

We have already discussed that a Blockchain is a growing list of records, called blocks, that are linked using cryptography.

But for taking advantage of all these purposes you need to take care of these working principals for Blockchain, those are as follows. This is how blockchain allows Bitcoin and other cryptocurrencies to operate without the need for a central authority. But it needs some principals and protocols operate in this manner. So let us check what are the working principals for Blockchain technology.

  1. The first step is to create a private key with the help of creating and digitally signing it. The private key is a type of data structure, which consists of the transfer value, sources, destinations, and many such trading purposes things.
  2. The second step is to propagate the data and transactions among all the members.
  3. The third step consists of the confirmation process.
  4. The fourth step is to make sure that future block starts linking with your blocks automatically. It is also a type of second confirmation phase.

What are the purposes of Blockchain?

The primary purpose of Blockchain is to provide a type of platform where users can rely on and can easily store their data safely without any issues. Moreover, you would be able to take advantage of money transfer and other such works, although there are a number of purposes for which the blockchain platform is being used.

Let us now have a look at some primary purposes of Blockchain.

  1. As the first purpose we discussed is that with the help of this platform, you would be able to store your data with complete security.
  2. You would be able to make trades with the help of this platform with the use of bitcoin and other means.
  3. You can even use this platform for neglecting the use of any third-party app. You may be knowing that while making any transaction, you don’t have to use any third-party app, the blockchain platform does everything on its own.
  4. It also offers it’s user a wholly secure and valid digital id which can be used for various means.
